It's a new implementation of the kinds of methods described in the "Cross-patch and STL meshing (Compounds)" reference section on gmsh website (see the bottom of the page). > What will it be capable of, and what is the approximate timeline for it? > It will be in Gmsh 4.0 - hopefully within the next couple of months. Gmsh 4.0 will bring many new features : a stable C++/C/Python API, a new efficient mesh file format (MSH4), a much faster mesh partitioning interface, improved OpenCASCADE integration, ...
